To all whom it may concern.'

Be it known that I, ALFRED CqPoNY', a subject to the Emperor of Austria, residing at thicago, Ain the county of Cook and State of illinois, have-invented new and'useful improvements .in Draft-Rigging for Rail way-Cars, `of which the following is aI full, clear, concise, and exact description, reference being had to the accompanying drawin,I forming 'a pal-t of this s eciication y invention relates to dra t ri ging for railway'cars, and more specificaly to the spring pocket and associated mechanism of such draft rigging.

Among the objects of my `invention is to provide a draft r1 ing which will be simple in construction, e cient in use and easy to nmnufncture and assemble.

In the ,drawings, in which I have shown one embodimentof my invention;F y

Figure 1 is a plan view of my improved draft rigging; p

Fig. 2 is a vertical section on the line 2 -2 of l4`ig.`l;`

Fig. 3 is a vertical sectionon the liie 3-3 of Fig. 1; l Y

Fig 4 is a side elevation ofone of the guide and abut-ment members; and

means. p l

Referring now to the drawings in detail l have shown my invention in connection willi the draft sills 1() of a carto each of which is'secured a cheek-plate forming a and abutment member 11,' a pair of loops or links 12 and' 13 of any suitable material `as castv steel located betweenl the sillsl() and'held in place and guided inthe members 11, a pair of followers 14capabl`e of engagement with the members 11 and between which thcjsprings 15 are held in place, a retaininglniember 15a`locatd begs to hold them cach otliel,'a draw bar 16 p l and 13 and a tie-plate 17 secured to the sills and located beneath the springs 15 for holding the latter in position. The abutment members 11 are similaiin all res ects and a description of one will be su cient. Each com )rises upper and lower abutments 19 for ta ing careof a pull on the draw bar, upper and lower alnitrnents` 20 for taking care ofthe strain due to the curved spring g. 5 is' a side elevation of the loops or links which embrace the shock absorbing member 15* cars being jammed together, and guide-ways or channels 20* for holding the loops 12 and 13 in placeand guiding them in their movement. The loops 12 and 13 lare also similar and each comprises an abutment portion 21. for engagement with one ,of the followers Y 14, a pair of side bars 22 located. within the guide-ways 20, :in abutment'. portion 23 for engagement with the head of the draw bar' 16, and spaced guiding and retaining Walls 24 which, together with the abutn'ient ponl tion 23, forms a paage through winch the draw bar 16 extends. Y

Each of the followers i4 comprises a pair of lugs 25 which extend within the coils of the springs 'l5 to hold the latter in position.v The springs 15 may be of any suitable construction, and, as shown, comprise inncji" and outer coil springs 26 and 27 located between the followers 14 and held in place iliereby. The retaining member 15 is located between the two sets of springs and formed withen aging portions 2S and 29, to assist in hol ing the springs in their proper relative position. The draw har 16 is provided with the usual coupling head 3U and the usual T-shaped head. 31 for engagement with the loops of the spring pocket.

The tioplate 17 is rovidsd with n curved portion 32 for hol ing thc springs l5 in position and preventing them from dropping out, and 1s secured to the sills 1t) in any suitable manner as by bolts 33. u

In assembling the draft rigging the loops. 12 and 13 are first placed in proper relative iosition with respect to the head of the draw .ar 16 with the drow bar. extending out through thc passage formed by the portions 23 and 24. VWith these partsthus :issembicd the loops 12 and 13 are then slipped cndwise. between the sills 10 and into the guidewys`- 20 until the abutment ortion'tl is sub# stantially even with the a utmcnts 20 on the members 11. The followers* when thus asse'm lef. are inserted in position within the loops 12 and 13 from beneath. After these parts 14, 15 and 15* have been placed in position the tie-I put in lace to hold the eiiringsfand'follow-I ers wit in the loops 12 and 1B and the tie. plate is secured to the sills -by inserting the bolts 33. The walls of the channels 20@ will f sembled in their roper relative position and l preventl the/loops 12 and 13 from separatinglo 14., Vretaining and springs 15 src then as 1in,-

so n

)late 17 is then lob from each other and will thus prevent the T-shaped head 31 of the draw bar from be- "coming disengaged and these walls also guide the loops 12 and 13 in their movement.

The operation ofrny improved draft rig-V ging which tend to move the conpllnghead 30 is as follows: IfA forces. arcexerted awa from the draft sills 1'0, the T- shaped hea 31 will exert a forceon the abutment 23 which will be transmitted to that follower 14 which is farthest from the draw bar through-the side bar 22 and abutment portion 21. This will cause a force y,to be exerted'on the other 'follower 1 4 through the springs 15 lwhich ilorce will be transmiti/ed to the s1lls 10 throughftfhe abutments 19 of the members 11. If forces'are exerted which tend to jam cars together the T- shaped head Pil-will exert a pressure on the follower 14 'with which it engages which y will be transmitted through the springs 15v I to 4the other follower 11i and through the abntments 2O of the members 11 tothe sills 10.

lt will be seen that I have provided a draft rigging 'which comprises few parts,

which can be very .easily 'assembled and which isof very rugged construction.

While I have shown and described a specic .form of shockV absorbing mechanism between the followers'lei it is obvious that any suitable form of shock absorbing mechanism may be used.

Having thusdescribed my invention what I'claimas new anddesi-re to secure by Letters Patent is l. The `combinationwith a draw'bar having 'a coupling head and a T-shaped head integral with said draw bar, the.` arms of said T-.shaped head extending substantially vertically, a pair of substantially parallel draft sills spaced from each other horizontally, and lyielding compressible shock absorbing means, of means for connecting said draw bal.'l to-said shock absorbin means comprising a. pair of loops locate in the space between said sills` embracing said shock absorbing means, one loop embracing one arm of the T-shaped head, and the other loop embracing the other arm, and means Vfor' holding said loops in position with respect to said T-shaped head supported. by said sills.

2. The combination with a draw bar having a eonpling head and a T-shaped head integral with said draw bar, the arms of said T-shaped head extending substantially vertical1y, a pair of substantially parallel (li-aft sills spaced. from each other horizontall-y; and yielding 'compressble shock absorbing means, of means for connecting Said draw bar to said. shock absoi'bin vmeans fcomprising a paix-'of loops locate s ace between said sills emzsracing said shock absorbingmeanaone loop embracing" one arm of the -shaped head, and the other vloopA embracing the other-farm, and means for holding said loops in position with respect to said T-shaped head land jllidin lthelam in ltheir movement 'supported y `saiY sils.
